Most `§X.Y Lnnn` citations no longer point at the text they name. Line numbers rot each time a draft is re-rendered for an erratum, and a citation resolving to the wrong paragraph is worse than none: it looks authoritative.

scripts/check-citations.py parses section spans out of each draft and asserts every cited range falls inside the section it names. It reproduces the survey in #18 -- 65 sections-not-found exactly, 674 vs 667 checked, the delta being citations a wider regex catches.

It splits on "\n" rather than using splitlines(), because drafts carry form-feed page separators that splitlines() also breaks on, drifting every line number further the deeper into the draft it sits. That bug makes correct citations look broken, and it is why this is a script with a reproduced baseline rather than a one-off measurement.

CI pins the count at 512 and fails in BOTH directions, so a new broken citation and a fixed-but-unlowered baseline are each caught. Re-keying the backlog stays separate work; this stops it rotting further.

Also drops parseGimmeCard's assert restating the check above it. parseIgotCard's remaining assert tests a different property and stays.
